I see the same problem in IDL 5.4-5.6 on win2k sp-3. This seems to be
limited to Win2k and WinXP right now but I suspect that it affects all
versions and Bill didn't notice the "bug" in your initial test code.
Somewhere someone at RSI must have defined an uint instead of a long...

I would report this to RSI if you haven't already.

I think there is little you can do beyond restarting your application every
few days and waiting for 5.7. Who knows, maybe they'll release 5.6.1?
